Introduction
General Description
McQuay air-cooled water chillers are complete, self-contained automatic refrigerating units.
Every unit is completely assembled, factory wired, charged, and tested. Each unit consists of
air-cooled condensers, Copeland Compliant Scroll

hermetic compressor, brazed plate-to-
plate evaporator, and complete refrigerant piping. Liquid line components include sight-
glass/moisture indicator, solenoid valve, and thermal expansion valve. Other features include
a compressor heater, and evaporator heater for chilled water freeze protection.
The electrical control center includes all equipment protection and operating controls
necessary for automatic operation. Condenser fan motors are three-phase (except single-phase
on No. 1 fan with SpeedTrol option) and started by their own contactors and have inherent
overload protection. Each compressor has solid-state motor protection for inherent thermal
overload protection except Model AGZ 010 that has internal line breakage.
